  • Elevation and index apparatus of water hydraulic driven type
    Patent number: 6453773
    Abstract: An elevation and index apparatus of a water hydraulic driven type has a rotary table (5) supported pivotally by a cross roller bearing (15), a water hydraulic motor (9) and a water hydraulic cylinder (8), each fixed to a table base (14) supporting a power transmission mechanism and the cross roller bearing (15), a main elevation shaft (7) connected to an output shaft of the water hydraulic cylinder (8), an elevation and index table (1) connected to the main elevation shaft (7) through a bearing (7a) and connected to the rotary table (5) so as to restrict pivotal movement, and a casing (18) disposed outside the table base (14) and enclosing the power transmission mechanism.

  • Storage and conveyance of heavy articles
    Patent number: 4971508
    Abstract: In a storage facility for heavy coils or the like, coils are transported to and from stationary rests by a first carriage which include a hydraulic lift. The first carriage is carried by a second carriage which moves perpendicularly to the path of the first carriage and which has its own heavy article-supporting rest. Transfer of heavy articles from rest to rest takes place by operation of the hydraulic lift in conjunction with lateral movement of the first carriage. The second carriage is self-propelled, and also carries a hydraulic pump unit for powering the lift through a flexible coupling which allows limited movement of the first carriage away from the second carriage. A third carriage, which is self-propelled and movable perpendicularly to the path of the second carriage, receives the second carriage to carry the second carriage, with a first carriage on it, to and away from the storage facility. The second and third carriages are movable independently of each other.

  • Method of preparing fine crystal particles of maleic anhydride
    Patent number: 4709057
    Abstract: A method of preparing fine crystal particles of maleic anhydride is provided. The method contains the steps of putting a molten mass of maleic anhydride into a hermetically closed container moved at a moving rate of 1 to 30 times per minute and cooling the molten mass to room temperature over three hours or more. A maleic anhydride composition contains 0.01 to 5 wt. parts of colloidal silica relative to 100 wt. parts of maleic anhydride particles.
